According to 1 Chronicles 11:23, how tall was the Egyptian whom Benaiah killed with his own spear?

Answer: Five cubits

Benaiah went against the huge Egyptian with a club, snatched the spear like a weaver's beam from his hand and killed him with it.

“He also struck down an Egyptian, a huge man five cubits tall. Although the Egyptian had a spear like a weaver’s beam in his hand, Benaiah went against him with a club, snatched the spear from his hand, and killed the Egyptian with his own spear.”— 1 Chronicles 11:23 (BSB)
